16 Allied Telesyn AT-8000S Switch CLI Reference Guide Chapter 1. Using the CLI Overview This chapter describes how to start using the CLI and the CLI command editing features. CLI s Introduction To assist in configuring the device, the Command Line Interface (CLI) is divided into different command modes. Each command mode has its own set of specific commands. Entering a question mark "?" at the system prompt (console prompt) displays a list of commands available for that particular command mode. From each mode a specific command is used to navigate from one command mode to another. The standard order to access the modes is as follows: User EXEC mode, Privileged EXEC mode, Global Configuration mode, and Interface Configuration mode. When starting a session, the initial mode is the User EXEC mode. Only a limited subset of commands are available in User EXEC mode. This level is reserved for tasks that do not change the configuration. To enter the next level, the Privileged EXEC mode, a password is required. The Privileged EXEC mode gives access to commands that are restricted on User EXEC mode and provides access to the device Configuration mode. The Global Configuration mode manages the device configuration on a global level. The Interface Configuration mode configures specific interfaces in the device. User EXEC Mode After logging into the device, the user is automatically in User EXEC command mode unless the user is defined as a privileged user. In general, the User EXEC commands allow the user to perform basic tests, and list system information. The user-level prompt consists of the device host name followed by the angle bracket (>). Console> The default host name is Console unless it has been changed using the hostname command in the Global Configuration mode. Privileged EXEC Mode Privileged access is password protected to prevent unauthorized use because many of the privileged commands set operating system parameters. The password is not displayed on the screen and is case sensitive. Privileged users enter directly into the Privileged EXEC mode. To enter the Privileged EXEC mode from the User EXEC mode, perform the following steps: 1. At the prompt enter the enable command and press <Enter>. A password prompt is displayed. Page 14

17 Using the CLI Overview 2. Enter the password and press <Enter>. The password is displayed as *. The Privileged EXEC mode prompt is displayed. The Privileged EXEC mode prompt consists of the device host name followed by #. Console# To return from the Privileged EXEC mode to the User EXEC mode, use the disable command. The following example illustrates how to access the Privileged EXEC mode and return to the User EXEC mode: Console> enable Enter Password: ****** Console# Console# disable Console> The exit command is used to return from any mode to the previous mode except when returning to the User EXEC mode from the Privileged EXEC mode. For example, the exit command is used to return from the Interface Configuration mode to the Global Configuration mode. Global Configuration Mode Global Configuration mode commands apply to features that affect the system as a whole, rather than just a specific interface. The configure Privileged EXEC mode command is used to enter the Global Configuration mode. To enter the Global Configuration mode perform the following steps: 1. At the Privileged EXEC mode prompt enter the configure command and press <Enter>. The Global Configuration mode prompt is displayed. The Global Configuration mode prompt consists of the device host name followed by (config) and #. Console(config)# To return from the Global Configuration mode to the Privileged EXEC mode, the user can use one of the following commands: exit end Ctrl+Z The following example illustrates how to access the Global Configuration mode and return to the Privileged EXEC mode: Console# Console# configure Console(config)# exit Console# Page 15

18 Allied Telesyn AT-8000S Switch CLI Reference Guide Interface Configuration and Specific Configuration Modes Interface Configuration mode commands modify specific interface operations. The following are the Interface Configuration modes: Line Interface Contains commands to configure the management connections. These include commands such as line timeout settings, etc. The line Global Configuration mode command is used to enter the Line Configuration command mode. VLAN Database Contains commands to create a VLAN as a whole. The vlan database Global Configuration mode command is used to enter the VLAN Database Interface Configuration mode. Management Access List Contains commands to define management access-lists. The management access-list Global Configuration mode command is used to enter the Management Access List Configuration mode. Ethernet Contains commands to manage port configuration. The interface ethernet Global Configuration mode command is used to enter the Interface Configuration mode to configure an Ethernet type interface. Port Channel Contains commands to configure port-channels, for example, assigning ports to a portchannel. Most of these commands are the same as the commands in the Ethernet interface mode, and are used to manage the member ports as a single entity. The interface port-channel Global Configuration mode command is used to enter the Port Channel Interface Configuration mode. SSH Public Key-chain Contains commands to manually specify other device SSH public keys. The crypto key pubkey-chain ssh Global Configuration mode command is used to enter the SSH Public Keychain Configuration mode. QoS Contains commands related to service definitions. The qos Global Configuration mode command is used to enter the QoS services configuration mode. MAC Access-List Configures conditions required to allow traffic based on MAC addresses. The mac access-list Global Configuration mode command is used to enter the MAC access-list configuration mode. Page 16

19 Using the CLI Starting the CLI Starting the CLI The device can be managed over a direct connection to the device console port or via a Telnet connection. The device is managed by entering command keywords and parameters at the prompt. Using the device Command Line Interface (CLI) is very similar to entering commands on a UNIX system. If access is via a Telnet connection, ensure that the device has a defined IP address, corresponding management access is granted, and the workstation used to access the device is connected to the device prior to using CLI commands. Note The following steps are for use on the console line only. To start using the CLI, perform the following steps: 1. Connect the DB9 null-modem or cross over cable to the RS-232 serial port of the device to the RS-232 serial port of the terminal or computer running the terminal emulation application. Note The default data rate is a) Set the data format to 8 data bits, 1 stop bit, and no parity. b) Set Flow Control to none. c) Under Properties, select VT100 for Emulation mode. d) Select Terminal keys for Function, Arrow, and Ctrl keys. Ensure that the setting is for Terminal keys (not Windows keys). Note When using HyperTerminal with Microsoft Windows 2000,ensure that Windows 2000 Service Pack 2 or later is installed. With Windows 2000 Service Pack 2, the arrow keys function properly in HyperTerminal s VT100 emulation. Go to for information on Windows 2000 service packs. 2. Enter the following commands to begin the configuration procedure: Console> enable Console# configure Console(config)# 3. Configure the device and enter the necessary commands to complete the required tasks. 4. When finished, exit the session with the exit command. When a different user is required to log onto the system, use the login Privileged EXEC mode command. This effectively logs off the current user and logs on the new user. Page 17

20 Allied Telesyn AT-8000S Switch CLI Reference Guide Editing Features Entering Commands A CLI command is a series of keywords and arguments. Keywords identify a command, and arguments specify configuration parameters. For example, in the command show interfaces status ethernet 1/e11, show, interfaces and status are keywords, ethernet is an argument that specifies the interface type, and 1/e11 specifies the port. To enter commands that require parameters, enter the required parameters after the command keyword. For example, to set a password for the administrator, enter: Console(config)# username admin password alansmith When working with the CLI, the command options are not displayed. The command is not selected from a menu, but is manually entered. To see what commands are available in each mode or within an interface configuration, the CLI does provide a method of displaying the available commands, the command syntax requirements and in some instances parameters required to complete the command. The standard command to request help is?. There are two instances where help information can be displayed: Keyword lookup The character? is entered in place of a command. A list of all valid commands and corresponding help messages are is displayed. Partial keyword lookup If a command is incomplete and or the character? is entered in place of a parameter. The matched keyword or parameters for this command are displayed. To assist in using the CLI, there is an assortment of editing features. The following features are described: Terminal Command Buffer Command Completion Nomenclature Keyboard Shortcuts Terminal Command Buffer Every time a command is entered in the CLI, it is recorded on an internally managed Command History buffer. Commands stored in the buffer are maintained on a First In First Out (FIFO) basis. These commands can be recalled, reviewed, modified, and reissued. This buffer is not preserved across device resets. Keyword Up-arrow key Ctrl+P Down-arrow key Description Recalls commands in the history buffer, beginning with the most recent command. Repeats the key sequence to recall successively older commands. Returns to more recent commands in the history buffer after recalling commands with the up-arrow key. Repeating the key sequence will recall successively more recent commands. By default, the history buffer system is enabled, but it can be disabled at any time. For information about the command syntax to enable or disable the history buffer, see history. There is a standard default number of commands that are stored in the buffer. The standard number of 10 commands can be increased to 216. By configuring 0, the effect is the same as disabling the history buffer system. For information about the command syntax for configuring the command history buffer, see history size. To display the history buffer, see show history. Page 18

21 Using the CLI Editing Features Negating the Effect of Commands For many configuration commands, the prefix keyword no can be entered to cancel the effect of a command or reset the configuration to the default value. This guide describes the negation effect for all applicable commands. Command Completion If the command entered is incomplete, invalid or has missing or invalid parameters, then the appropriate error message is displayed. This assists in entering the correct command. By pressing the <Tab> button, an incomplete command is entered. If the characters already entered are not enough for the system to identify a single matching command, press? to display the available commands matching the characters already entered. Nomenclature When referring to an Ethernet port in a CLI command, the following format is used: For an Ethernet port on a standalone device: Ethernet_type port_number For an Ethernet port on a stacked device: unit_number/ethernet_type port number The Ethernet type may be Gigabit Ethernet (indicated by g ) or Fast Ethernet (indicated by e ). For example, g3 stands for Gigabit Ethernet port 3 on a stand-alone device, and e3 stands for Fast Ethernet port 3 on a stand-alone device, whereas 1/g3 stands for Gigabit Ethernet port 3 on stacking unit 1 and 1/e3 stands for Fast Ethernet port 3 on stacking unit 1. The ports may be described on an individual basis or within a range. Use format port number-port number to specify a set of consecutive ports and port number,port number to indicates a set of non-consecutive ports. For example, g1-3 stands for Gigabit Ethernet ports 1, 2 and 3, and g1,5 stands for Gigabit Ethernet ports 1 and 5. Keyboard Shortcuts The CLI has a range of keyboard shortcuts to assist in editing the CLI commands. The following table describes the CLI shortcuts. Keyboard Key Up-arrow key Down-arrow key Ctrl+A Ctrl+E Ctrl+Z / End Backspace key Description Recalls commands from the history buffer, beginning with the most recent command. Repeat the key sequence to recall successively older commands. Returns the most recent commands from the history buffer after recalling commands with the up arrow key. Repeating the key sequence will recall successively more recent commands. Moves the cursor to the beginning of the command line. Moves the cursor to the end of the command line. Returns back to the Privileged EXEC mode from any configuration mode. Deletes one character left to the cursor position. Page 19

22 CLI Command Conventions When entering commands there are certain command entry standards that apply to all commands. The following table describes the command conventions. Convention Description [ ] In a command line, square brackets indicates an optional entry. { } In a command line, curly brackets indicate a selection of compulsory parameters separated by the character. One option must be selected. For example: flowcontrol {auto on off} means that for the flowcontrol command either auto, on or off must be selected. Italic font Indicates a parameter. <Enter> Indicates an individual key on the keyboard. For example, <Enter> indicates the Enter key. Ctrl+F4 Any combination keys pressed simultaneously on the keyboard. Screen Display Indicates system messages and prompts appearing on the console. all When a parameter is required to define a range of ports or parameters and all is an option, the default for the command is all when no parameters are defined. For example, the command interface range port-channel has the option of either entering a range of channels, or selecting all. When the command is entered without a parameter, it automatically defaults to all. Copying and Pasting Text Up to 1000 lines of text (i.e., commands) can be copied and pasted into the device. Note It is the user s responsibility to ensure that the text copied into the device consists of legal commands only. This feature is dependent on the baud rate of the device. Note The default device baud rate is 115,200 When copying and pasting commands from a configuration file, make sure that the following conditions exist: A device Configuration mode has been accessed. The commands contain no encrypted data, like encrypted passwords or keys. Encrypted data cannot be copied and pasted into the device.

24 Allied Telesyn AT-8000S Switch CLI Reference Guide Chapter 2. AAA Commands aaa authentication login The aaa authentication login Global Configuration mode command defines login authentication. To return to the default configuration, use the no form of this command. aaa authentication login {default list-name} method1 [method2...] no aaa authentication login {default list-name} default Uses the listed authentication methods that follow this argument as the default list of methods when a user logs in. list-name Character string used to name the list of authentication methods activated when a user logs in. (Range: 1-12 characters). method1 [method2...] Specify at least one from the following table: Keyword enable line local none radius tacacs Description Uses the enable password for authentication. Uses the line password for authentication. Uses the local username database for authentication. Uses no authentication. Uses the list of all RADIUS servers for authentication. Uses the list of all TACACS+ servers for authentication. The local user database is checked. This has the same effect as the command aaa authentication login listname local. Note On the console, login succeeds without any authentication check if the authentication method is not defined. Global Configuration mode Page 22

25 AAA Commands The default and optional list names created with the aaa authentication login command are used with the login authentication command. Create a list by entering the aaa authentication login list-name method command for a particular protocol, where list-name is any character string used to name this list. The method argument identifies the list of methods that the authentication algorithm tries, in the given sequence. The additional methods of authentication are used only if the previous method returns an error, not if it fails. To ensure that the authentication succeeds even if all methods return an error, specify none as the final method in the command line. The following example configures the authentication login. Console(config)# aaa authentication login default radius local enable none aaa authentication enable The aaa authentication enable Global Configuration mode command defines authentication method lists for accessing higher privilege levels. To return to the default configuration, use the no form of this command. aaa authentication enable {default list-name} method1 [method2...] no aaa authentication enable {default list-name} default Uses the listed authentication methods that follow this argument as the default list of methods, when using higher privilege levels. list-name Character string used to name the list of authentication methods activated, when using access higher privilege levels (Range: 1-12 characters). method1 [method2...] Specify at least one from the following table: Keyword enable line none radius tacacs Description Uses the enable password for authentication. Uses the line password for authentication. Uses no authentication. Uses the list of all RADIUS servers for authentication. Uses username $enabx$., where x is the privilege level. Uses the list of all TACACS+ servers for authentication. Uses username "$enabx$." where x is the privilege level. If the default list is not set, only the enable password is checked. This has the same effect as the command aaa authentication enable default enable. On the console, the enable password is used if it exists. If no password is set, the process still succeeds. This has the same effect as using the command aaa authentication enable default enable none. Page 23

26 Allied Telesyn AT-8000S Switch CLI Reference Guide Global Configuration mode The default and optional list names created with the aaa authentication enable command are used with the enable authentication command. The additional methods of authentication are used only if the previous method returns an error, not if it fails. To ensure that the authentication succeeds even if all methods return an error, specify none as the final method in the command line. All aaa authentication enable default requests sent by the device to a RADIUS or TACACS+ server include the username $enabx$., where x is the requested privilege level. The following example sets the enable password for authentication when accessing higher privilege levels. Console(config)# aaa authentication enable default enable login authentication The login authentication Line Configuration mode command specifies the login authentication method list for a remote telnet or console. To return to the default configuration specified by the aaa authentication login command, use the no form of this command. login authentication {default list-name} no login authentication default Uses the default list created with the aaa authentication login command. list-name Uses the indicated list created with the aaa authentication login command. Uses the default set with the command aaa authentication login. Line Configuration mode Changing login authentication from default to another value may disconnect the telnet session. The following example specifies the default authentication method for a console. Console(config)# line console Console(config-line)# login authentication default Page 24

27 AAA Commands enable authentication The enable authentication Line Configuration mode command specifies the authentication method list when accessing a higher privilege level from a remote telnet or console. To return to the default configuration specified by the aaa authentication enable command, use the no form of this command. enable authentication {default list-name} no enable authentication default Uses the default list created with the aaa authentication enable command. list-name Uses the indicated list created with the aaa authentication enable command. Uses the default set with the aaa authentication enable command. Line Configuration mode There are no user guidelines for this command. The following example specifies the default authentication method when accessing a higher privilege level from a console. Console(config)# line console Console(config-line)# enable authentication default ip http authentication The ip http authentication Global Configuration mode command specifies authentication methods for HTTP server users. To return to the default configuration, use the no form of this command. ip http authentication method1 [method2...] no ip http authentication method1 [method2...] Specify at least one from the following table: Keyword local none Description Uses the local username database for authentication. Uses no authentication. Page 25

32 Allied Telesyn AT-8000S Switch CLI Reference Guide Chapter 3. Address Table Commands bridge address The bridge address Interface Configuration (VLAN) mode command adds a MAC-layer station source address to the bridge table. To delete the MAC address, use the no form of this command. bridge address mac-address {ethernet interface port-channel port-channel-number} [permanent delete-onreset delete-on-timeout secure] no bridge address [mac-address] mac-address A valid MAC address. interface A valid Ethernet port. port-channel-number A valid port-channel number. permanent The address can only be deleted by the no bridge address command. delete-on-reset The address is deleted after reset. delete-on-timeout The address is deleted after "age out" time has expired. secure The address is deleted after the port changes mode to unlock learning (no port security command). This parameter is only available when the port is in the learning locked mode. No static addresses are defined. The default mode for an added address is permanent. Interface Configuration (VLAN) mode Using the no form of the command without specifying a MAC address deletes all static MAC addresses belonging to this VLAN). The following example adds a permanent static MAC-layer station source address 3aa2.64b3.a245 on port 1/e16 to the bridge table. Console(config)# interface vlan 2 Console(config-if)# bridge address 3aa2.64b3.a245 ethernet 1/e16 permanent bridge multicast filtering The bridge multicast filtering Global Configuration mode command enables filtering multicast addresses. To disable filtering multicast addresses, use the no form of this command. Page 30

33 Address Table Commands bridge multicast filtering no bridge multicast filtering Filtering multicast addresses is disabled. All multicast addresses are flooded to all ports. Global Configuration mode If multicast devices exist on the VLAN, do not change the unregistered multicast addresses state to drop on the switch ports. If multicast devices exist on the VLAN and IGMP-snooping is not enabled, the bridge multicast forward-all command should be used to enable forwarding all multicast packets to the multicast switches. In this example, bridge multicast filtering is enabled. Console(config)# bridge multicast filtering bridge multicast address The bridge multicast address Interface Configuration (VLAN) mode command registers a MAC-layer multicast address in the bridge table and statically adds ports to the group. To unregister the MAC address, use the no form of this command. bridge multicast address {mac-multicast-address ip-multicast-address} bridge multicast address {mac-multicast-address ip-multicast-address} [add remove] {ethernet interface-list port-channel port-channel-number-list} no bridge multicast address {mac-multicast-address ip-multicast-address} add Adds ports to the group. If no option is specified, this is the default option. remove Removes ports from the group. mac-multicast-address A valid MAC multicast address. ip- multicast-address A valid IP multicast address. interface-list Separate nonconsecutive Ethernet ports with a comma and no spaces; a hyphen is used to designate a range of ports. port-channel-number-list Separate nonconsecutive port-channels with a comma and no spaces; a hyphen is used to designate a range of ports. No multicast addresses are defined. Page 31

34 Allied Telesyn AT-8000S Switch CLI Reference Guide Interface configuration (VLAN) mode If the command is executed without add or remove, the command only registers the group in the bridge database. Static multicast addresses can only be defined on static VLANs. s The following example registers the MAC address: Console(config)# interface vlan 8 Console(config-if)# bridge multicast address 01:00:5e:02:02:03 The following example registers the MAC address and adds ports statically. Console(config)# interface vlan 8 Console(config-if)# bridge multicast address 01:00:5e:02:02:03 add ethernet 1/e1-e9, 2/e2 bridge multicast forbidden address The bridge multicast forbidden address Interface Configuration (VLAN) mode command forbids adding a specific multicast address to specific ports. Use the no form of this command to return to the default configuration. bridge multicast forbidden address {mac-multicast-address ip-multicast-address} {add remove} {ethernet interface-list port-channel port-channel-number-list} no bridge multicast forbidden address {mac-multicast-address ip-multicast-address} add Adds ports to the group. remove Removes ports from the group. mac-multicast-address A valid MAC multicast address. ip- multicast-address A valid IP multicast address. interface-list Separate nonconsecutive Ethernet ports with a comma and no spaces; hyphen is used to designate a range of ports. port-channel-number-list Separate nonconsecutive valid port-channels with a comma and no spaces; a hyphen is used to designate a range of port-channels. No forbidden addresses are defined. s Interface Configuration (VLAN) mode Page 32

35 Address Table Commands Before defining forbidden ports, the multicast group should be registered. s In this example, MAC address e is forbidden on port 2/e9 within VLAN 8. Console(config)# interface vlan 8 Console(config-if)# bridge multicast address e Console(config-if)# bridge multicast forbidden address e add ethernet 2/e9 bridge multicast forward-all The bridge multicast forward-all Interface Configuration (VLAN) mode command enables forwarding all multicast packets on a port. To restore the default configuration, use the no form of this command. bridge multicast forward-all {add remove} {ethernet interface-list port-channel port-channel-number-list} no bridge multicast forward-all add Force forwarding all multicast packets. remove Do not force forwarding all multicast packets. interface-list Separate nonconsecutive Ethernet ports with a comma and no spaces; a hyphen is used to designate a range of ports. port-channel-number-list Separate nonconsecutive port-channels with a comma and no spaces; a hyphen is used to designate a range of port-channels. This setting is disabled. Interface Configuration (VLAN) mode There are no user guidelines for this command. In this example, all multicast packets on port 1/e8 are forwarded. Console(config)# interface vlan 2 Console(config-if)# bridge multicast forward-all add ethernet 1/e8 bridge multicast forbidden forward-all The bridge multicast forbidden forward-all Interface Configuration (VLAN) mode command forbids a port to be a forward-all-multicast port. To restore the default configuration, use the no form of this command. Page 33

36 Allied Telesyn AT-8000S Switch CLI Reference Guide bridge multicast forbidden forward-all {add remove} {ethernet interface-list port-channel port-channelnumber-list} no bridge multicast forbidden forward-all add Forbids forwarding all multicast packets. remove Does not forbid forwarding all multicast packets. interface-list Separates nonconsecutive Ethernet ports with a comma and no spaces; a hyphen is used to designate a range of ports. port-channel-number-list Separates nonconsecutive port-channels with a comma and no spaces; a hyphen is used to designate a range of port-channels. This setting is disabled. Interface Configuration (VLAN) mode IGMP snooping dynamically discovers multicast device ports. When a multicast device port is discovered, all the multicast packets are forwarded to it unconditionally. This command prevents a port from becoming a multicast device port. In this example, forwarding all multicast packets to 1/e1 with VLAN 2 is forbidden. Console(config)# interface vlan 2 Console(config-if)# bridge multicast forbidden forward-all add ethernet 1/e1 bridge aging-time The bridge aging-time Global Configuration mode command sets the address table aging time. To restore the default configuration, use the no form of this command. bridge aging-time seconds no bridge aging-time seconds Time in seconds. (Range: seconds) The default setting is 300 seconds.
